i have to do a science project, so i'm just wondering if the rock quartz is the same as the rock granite. please help!!!!!!!
I would think that this would be classified as a granite, at least a granitoid (which is a granitic like rock that includes some siliceous diorites). All granites have quartz, orthoclase and plagioclase, and almost always biotite mica. Were there flecks of black flat biotites in the rock? If not, you might have something weird that is super siliceous.
Syenite is undersaturated in silica meaning no quartz or an particularly little quantity. relies upon on how choosy you want to be yet via definition syenite skill no quartz seen. so because it rather is incorrect. Granite is right. and because each little thing that had those 2 minutes is frequently lumped as granite i might say granodiorite is the subsequent suited suited. greater valuable then syenite in any case.
rock man, The most probable answer to your question is granite, but there are several other categories of rock (that need only contain quartz and feldspars) that are considerably less common. It depends on the relative amounts of quartz, alkali feldspar, and plagioclase feldspar. If you click the link below and find your rock's approximate composition on the upper half of the diagram
